Prayer Circles

I've recently reunited with my husband of 14 yrs after being seperated for 3 of those yrs. It hasn't been 3 months yet and we're already in trouble. I've prayed and tried to be strong but always let the anger come out. I guess I'm having a problem knowing if this is what I shouldn've done. We're both believers although he's not active in church at all right now. He's doing more for others and not really looking at home. We argue and wind up angry too often. I need advise and prayers from you. A question I have is that he is closer to a family member than to me. Show more attention, words and interest in her are kinder. Friends and others thought that she was a "friend" he dated. I'm having a hard time accepting and feeling like I have tocompete with her. Is my thinking wrong? What can/should I do?
